The founding fathers were NOT rabid conspiracy theorists who hate the government (they founded it, after all) want to abolish ALL taxes (as if that's possible) but still uphold the Constitution of the United States, at least as it was originally written, because the Constitution is the basis of our government (which they claim to hate).
Most Libertarians are not "conspiracy theorists." Go to the Libertarian Party website:
...and find some "conspiracy theories."
And as far as "hating the government"...the founders of this country would UNQUESTIONABLY hate this CURRENT government. They committed armed rebellion against a government that was a tiny, tiny fraction of the size and tyranny of the current government.
Did you know that total federal spending in 1860 (the year before the Civil War) was something like $65 MILLION dollars? That works out to about $1.3 BILLION dollars, in today's terms. Current federal spending is over $2 TRILLION, or more than a factor of 1000 times the size of the federal governmnent before the Civil War.
The government that the Founders drew up had NO income taxes (income taxes for government at all levels is now approximately 40 percent of the national income). There was NO standing army...let alone a standing army with troops in 100 different countries. The federal government that the Founders created allowed the federal government to own NO land...outside of the 10 miles square of the District of Columbia, and federal forts. The current federal government own 30 PERCENT of all the land in the United States!
The only difference between Libertarians and the Founders is that we Libertarians sign a pledge to forswear violence as a means of political change. The Founders would have staged an armed rebellion a long time ago. There's no way they would have accepted the government (particularly the federal government) massively violating the Constitution, as it currently does.
but still uphold the Constitution of the United States, at least as it was originally written, because the Constitution is the basis of our government...
Yes, if the federal government followed the Constitution, many, if not most, Libertarians would be satisfied. We most certainly COULD do that (follow the Constitution) without ANY taxes on income (including earned income, capital gains, or corporate income) because this country DID do that for over 130 years after it was founded. The answer is to DRAMATICALLY cut federal spending, including complete elimination of ALL unconstitutional federal departments (Education, Energy, Interior, Agriculture, Labor, Health and Human Services, and so on).
